WIN DING DEVICE FOR CLOCKS.

Application filed March 9, 1915.

To all whom it may concern: 7

Be it known that 1, WILLIAM ENDLICH, a citizen of the United States,residing at Kewaskum, in the county of Washington and State of\Visconsin, have invented new and useful Improvements in lVindingDevices for Clocks, of which the following is a specification.

The invention relates to a winding device, and more particularly to theclass of ratchet keys for winding arbors of main springs of clocks.

The primary object of the invention is the provision of a ratchet key ofthis character wherein the main spring for clock mechanism can beconveniently wound upon its an bor for the placing of a ring or yoke onthe spring so that the latter can be removed from the clock mechanismfor repairing the same.

Another object of the invention is the provision of a ratchet key ofthis character wherein the ratchet wheel can be readily re versed sothat either main spring for the time or striking mechanism of a clockcan be conveniently wound when repairing the same, the key being ofnovel form, and the ratchet wheels for use therewith are interchangeableso that the key is adaptable to different sizes of spring arbors.

A further object of the invention is the provision of a key of thischaracter which is simple in construction, thoroughly reliable andeflicient in operation, strong, durable, and inexpensive in manufacture.

With these and other objects in view, the invention consists in theconstruction, combination and arrangement of parts as will behereinafter fully described, illustrated in the accompanying drawing,and pointed out in the claim hereunto appended.

In the drawing: Figure 1 is a side elevation of a ratchet keyconstructed in accordance with the invention. Fig. 2 is a sectional viewon the line 22 of Fig. 1. Fig. 3 is a rear elevation thereof. Fig. 4 isan edge elevation of the same.

Specification of Letters Patent.

Serial No. 13,185.

while mounted in the latter and projecting from one face thereof onopposite sides of the slot 7 are spaced guide lugs 8 between which areslidably fitted an extensible handle 9 in which is threaded a set screw10, the same being passed through the slot 7 and has its head workingagainst a washer 11 which bridges the slot 7 and frictionally engagesone face of the stem or shank 6, and in this manner the handle 9 isfastened in adjusted position.

Formed in the head 5 is an opening or hole 12 in which is removablyengaged one end of the hub 13 of a ratchet wheel 14, the hub beingformed with a squared opening 15 corresponding to the size of thesquared end of a main spring arbor for either the striking or timemechanism of a clock. Pivoted upon the head 5 are spaced reverselyacting ratchet pawls 16 and 17 respectively, the pawls 16 being adaptedto engage the teeth of the ratchet wheel 14 for locking the same againstrotation in one direction, yet permitting it to freely rotate in theopposite direction, while the other pawl is adapted to engage the teethof the wheel 14 to lock it against rotation in one direction when saidwheel is reversed and thereby permit the ratchet connection for thewinding of main springs in clocks in event that one spring necessarilywinds in one direction, while the other spring winds in the reversedirection. It is of course understood that the wheel 14 can be detachedso that it may be reversed, and the pawls 16 and 17 will lock it ineither of its adjusted positions on the reversal thereof. Fixed upon thehead 5 is a wire spring 18, the ends of which engage the respectivepawls 16 and 17 to hold the same in active position relative to thewheel 14 for the positive locking of the wheel during the use of theratchet key.

Detachably fixed upon the stem or shank 6 and extended over the hub 18of the wheel 11 is a guard 19 which prevents the accidentaldisengagement of the hub 13 from the hole 12 in the head 5 of the key,the guard 19 being provided with a hole 20 registering with the opening15 in the hub 13 of the wheel 11 so as not to interfere with theengagement of the ratchet wheel on the main spring arbor when the key isto be used for the winding of the main spring in a clock. It is ofcourse to be understood that ratchet wheels 14 having diflerent sizes ofopenings l-5 therein Will be used, and for this reason the said Wheel14: is detachably mounted upon the key so that the Wheel having theproper openingcan be substituted for the fitting ofthe same on the keyend of the main spring. arbor, and thus in this manner the key can beemployed for the Winding of main springs with 'arbors of different sizesat their key'engaging ends. The extension of *close relation to eachother in the time andstriking mechanism of a clock.- I From theforego1ng description, taken in 7 connection With the accompanyingdrawing,

the construction and manner ofoperation of ":2 the device Will beclearly understood, and

Y Copies of this patent may be obtained for five cents each, byaddressing the Commissioner of ratnts. 7

therefore a more extended explanation has been omitted. -What is claimedis:

A device of the class described comprising a body having a fiat headportion and a=rec -25 tangularshank extending at right angles to saidhead'portion, a ratchet device mounted on said head, a metallic striphaving one-end; secured to sa d shank and itsremaining end I arranged tohold said deviceupon said head,- 30

tWo series of headed studsv secured to said shank in parallel relationand a handle held in sliding contact With oneiside of said shank by saidstuds. 7
